Device for guiding flat or sheet-like copies in folders

Abstract

A device for guiding sheet-like copies which are severed from a material web in a cutting nip of a cutting-cylinder pair, including a copy guide disposed in an outlet wedge of the cutting-cylinder pair for gripping leading ends of the sheet-like copies for guiding the copies, the copy guide including revolving transport elements, and actuating drives for displacing the revolving transport elements in a lateral direction so as to adapt the transport elements to different positions and widths of material webs.

We claim:  
     
       1. A device for guiding sheet-like copies which are severed from a material web in a cutting nip of a cutting-cylinder pair, comprising a copy guide disposed in an outlet wedge of the cutting-cylinder pair for gripping leading ends of the sheet-like copies for guiding the copies, said copy guide including revolving transport elements, and actuating drives for displacing said revolving transport elements in a lateral direction so as to adapt said transport elements to different positions and widths of material webs. 
     
     
       2. The guiding device according to  claim 1 , wherein a respective copy guide is assigned to each side region of the material web. 
     
     
       3. The guiding device according to  claim 2 , wherein a plurality of the copy guides arranged on both sides of the material web which is to be processed are displaceable symmetrically in relation to a machine center. 
     
     
       4. The guiding device according to  claim 2 , wherein the copy guides arranged on both sides of the material web which is to be processed are displaceable independently of one another in relation to the machine center. 
     
     
       5. The guiding device according to  claim 1 , wherein to the copy guide there is assigned an actuating drive for positioning the copy guide within a displacement distance in a region of a side edge of the material web in accordance with the width of a copy. 
     
     
       6. The guiding device according to  claim 1 , wherein the copy guide includes pairwise driven rotary bodies and driving rotary bodies, about which said transport elements are revolvable. 
     
     
       7. The guiding device according to  claim 6 , including drives integrated in said copy guides for driving said driving rotary bodies. 
     
     
       8. The guiding device according to  claim 6 , wherein each copy guide comprises an actuating cylinder for displacing a mount including rotary bodies into a position wherein the material web is gripped thereby, and into a position wherein the material web is not gripped thereby. 
     
     
       9. The guiding device according to  claim 6 , wherein pairs of said rotary bodies, respectively, are formed with a gap having a variable opening between the rotary bodies thereof. 
     
     
       10. The guiding device according to  claim 9 , wherein said gap is bounded by said driven transport elements. 
     
     
       11. The guiding device according to  claim 9 , including pivotable carriers wherein said driven rotary bodies are accommodated, relative to the rotary bodies, respectively, which drive them. 
     
     
       12. The guiding device according to  claim 11 , wherein said pivotable carriers are pivotable relative to said driving rotary bodies in order to vary the extent of opening of said gap. 
     
     
       13. The guiding device according to  claim 1 , wherein said transport elements are configured as axially spaced-apart transport belts. 
     
     
       14. The guiding device according to  claim 1 , wherein the material web leaving the cutting nip is guidable by said transport elements on both sides of the material web, without any relative speed, along a gripping region. 
     
     
       15. The guiding device according to  claim 1 , wherein said driven transport elements are arranged on mutually opposite sides of the material web and on both sides of the material web. 
     
     
       16. A folder having a guiding device for guiding a material web in a cutting nip of a cutting-cylinder pair, wherein sheet-like copies are severed from the material web, comprising a copy guide disposed in an outlet wedge of the cutting-cylinder pair gripping leading ends of sheet-like copies severed from the web for guiding the copies, said copy guide including revolving transport elements, and actuating drives for displacing said revolving transport elements in a lateral direction so as to adapt said transport elements to different positions and widths of material webs.
